Construction and application of enhanced recovery after surgery-optimized management system with nurse-led multidisciplinary cooperation.

AIM: To evaluate the effect of enhanced recovery after surgery (ERAS)-optimized management system with nurse-led multidisciplinary cooperation. DESIGN: A quasi-experimental design. METHODS: Nursing department cooperated with medical and clinical department to establish an ERAS-optimized management system. After the system was developed, it was applied in surgical departments of the hospital. Using convenience sampling, 220 selective surgical patients, 82 nurses and 98 doctors from January 1st, 2021 to July 31st, 2021 were selected as the trial group. 220 selective surgical patients, 82 nurses and 98 doctors were selected as the control group from January 1st, 2020 to July 31st, 2020. ERAS observation indicators were compared between the two groups before and 6 months after implementation. The nurse professional identity scores and satisfaction of medical cooperation scores of the two groups at different time points were analysed by repeated analysis of variance. RESULTS: After the implementation, ERAS observation indicators in the trial group were better than the control group (p < 0.05). There were significant differences in the group main effect, time main effect and interaction effect of nurse professional identity scores, satisfaction of medical cooperation scores and scores in all dimensions between the two groups (p < 0.05). The scores of the experimental group at 3 months and 6 months after implementation were better than those of the control group (p < 0.05). CONCLUSIONS: Enhanced recovery after surgery-optimized management system with nurse-led multidisciplinary cooperation was an effective working method. It could promote patients recovery and enhance nurse professional identity.

Activity of the enzymes of the antioxidative system in cadmium-treated Oxya chinensis (Orthoptera Acridoidae).

One purpose in this research was to determine the toxic effects of Cd on antioxidant enzymes of Oxya chinensis (Orthoptera: Acridoidae). Changes in the activities of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and guaiacol peroxidase (GPx) were measured in O. chinensis insects injected with Cd(2+). Fifth-nymphs of O. chinensis insects were injected with Cd(2+) at different concentrations (0, 0.55×10(-4), 1.10×10(-4), 1.65×10(-4), 2.20×10(-4), and 2.75×10(-4)gg(-1)). An increase in SOD activity in O. chinensis was observed at 1.10×10(-4) to 2.75×10(-4)gg(-1) Cd(2+). The SOD activity was lower at 2.20×10(-4)and 2.75×10(-4)gg(-1) than that at 1.10×10(-4) and 1.65×10(-4)gg(-1). It appears that SOD had a positive protective effect at low Cd(2+) concentrations, and that this effect disappeared at high Cd(2+) concentrations. CAT activity was accelerated to varying degrees at 1.10×10(-4) to 2.75×10(-4)gg(-1) for males and at 1.10×10(-4), 2.20×10(-4), and 2.75×10(-4)gg(-1) for females. CAT showed a strong detoxification effect with all treatments. GPx activity decreased with increasing Cd(2+) concentration with all treatments for males and at 2.20×10(-4) and 2.65×10(-4)gg(-1) for females. We showed that GPx activity had a weak detoxification function with all treatments for males and at high Cd(2+) for females. Thus, CAT had a strong detoxification effect, whereas SOD had a medium and GPx had a weak detoxification effect. Among the three enzymes, CAT played an important role in the damaging mechanisms of reactive oxygen species in O. chinensis insects. Alterations of the antioxidant enzyme level under environmental stresses are suggested as indicators of biotic and abiotic stress.
